301mm M00. JOHNSTONE, or ROSELLE PARK, NEW, JERSEY, As'srcivon; 'r'o'cAMn oN MACHINE COMPANY, or BROOKLYN, NEW YORK, A donroan'rron or NEWYORK COMBINED SLITTING AND WINDING MACHINE Application filed August 29,192 1. Serial No. 734,845.

This invention relates to surface winding machines, and 1s morepart1cularly an improvement on the drlvlngmechanlsm shown in Patent No.1,465,967 of August 28, 1923.

In that patent one of the surface winding drums carries an extensionwhich forms the power shaft and from which other elements of the machineare driven. The main object and feature of this invention is to simplifythis construction and to render the power unit entirely independent ofthe winding machine proper to the end that the power unit and thewinding machine can be independently assembled and thereafter readilylined up and interconnected.

In the accompanying drawings the invention is disclosed in a concreteand preferred form in which: i

Fig. 1 is a general view in side elevation of a Winding and slittingmachine embodying the invention, with parts broken away and in sectionfor the sake of' clearness of illustration. 7

Fig. 2 is a plan view of one form of an intermediate means fortransmitting motion from the power unit to the riding -roll.

Fig. 3 is a vertical longitudinal sectional view on the plane of line3-,3 of Fig. 4.

Fig. 4: is a vertical transverse sectional view on the plane of line4-4: of Fig. 1.

In the embodiment of the invention here disclosed 1 indicates a mainframe of any suitable construction in which are mounted two windingdrums 2 and 3 spaced apart and rotating in the same direction. Thesedrums act against the wound material 1 on winding shaft 5. 6 is a toppressure or riding roll in a plane above the winding drums andintermediate the same. The winding shaft and riding roll are so mountedin the main frame as to rise as the diameter of the wound materialincreases in a manner well understood. Suitable slitting means areemployed consisting of 'complementary cutting means of the score cuttype. In the present instance a backing roll 7 is mounted in the mainframe and associated with this backing roll is one or more score cutters8.

The material 9, to be acted upon, is led into' 'the machine, in anysuitable way and may pass over guide 10', thence between the slittingelements and thence over'one of the drums to the windingshaft; v

f On the end of each winding drum. is a spur gear lljand on the endofthe "backing roll is likewise'aspur gear 12. These gears projectbeyond the main frame. Located adjacent the main frame at the side wherethe gears of the drums and slitting element project' is a'sub'sidiaryframe' 13 which may be bolted to the main frame as at'14. Thissubsidiary frame carries the power unit.

Injthe'present instance this power unit con- 'sists' of a; power shaft15 mountedin'bearing's'16 of the subsidiary frame". Motion is impartedto'th'e power shaft by any suitable means but preferably a'pulley 17 or'other power element and a clutch18 are used. .A brake pulley'19 is alsoassociated with the shaft. The construction andmdd'e of'oper ation'of'these parts. need not be described as they are fully" set .forth inPatent No."

1,465,967. Power shaft 15 islocatedin a plane'betweenthe two windingdrums so that spur: gear 20 on'5saidshaft'15 will en,

gage and drive spur'gearsll, 11 011 the 'winding drums and will alsoengage and drivesnur'gear 12 on backing roll ,7-

' "It will now be understood thatthe parts of the" power unit may beassembled independently' oflthos'e comprising the winding machines,after which the power unit is lined up with the winding mechanism. Thisfeature is ofgre'atadvantage in erecting the machine in the field, andalso-when it is de-' sired to changefrom a'lefthand to a right handmachine or vice versa- It is customary to meansof'avertical shaft 21,mounted in the main fra-me, and sliding bevel gears' 2 2.

This}shaftfherefextendsin a plane. between the winding '--drumsintermediate the ends of the drums. or main frame and the gears carriedby said drums. On the lower end of shaft 21 is a bevel gear 23 which maybe driven in any suitable way'such as by a bevel gear carried by spurgear 20. In this case it is preferred to mount a stud 24 in the mainframe substantially in line with drive" the riding rollby' gear 20 andto mount thereon a bevel gear 25 that meshes with bevel gear 23. Bevelgear 25 is provided with a slot 26 and gear 20 carries a dog 27 engagingsaid slot. This intermediate mechanism or dog and slot connection issomewhat flexible so that slight inaccuracies in lining up the parts arecompensated for. The bevel gear may be mount-v ed on the stud in anysuitable way, but preferably a'retaining collar 28 and a thrust washer29 areused so that end thrust in either direction may be taken up.

I claim:

1. A combined slitting and surface winding machine including: twosurface winding r rums spaced apart and rotating in the same direction,slitting means including a rotating element and score-cut slitters, agear on the end of each drum, a gear on the rotating element, a powershaft located below and intermediate the gears on the winding drums, agear on the power shaft meshing with the gears on the winding drums'andon the rotating element and transmitting power to all of said gears, ariding roll above the winding drums and intermediate the same, avertical shaft for driving the riding roll extending downwardly in aplane between the two winding drums and intermediate the ends of thedrums and their gears, a bevel I gear at the lower end of said verticalshaft, and a bevel gear moving with the gear on the power shaft andengaging the bevel gear on the vertical shaft. y

2. A combined slitting and surface Winding machine including: a mainframe, two surface winding drums spaced apart and rotating in the samedirection carried by said main frame, slitting means including arotating element and score-cut slitters also carried by saidmain frame,a gear on the end of each drum and projecting beyond said main frame, agear on the rotating element also projecting beyond said main frame, asubsidiary frame adjacent the main frame at the point where the gears onthe drums and rotating element project from the latter, and a powerunit, carried by said subsidiary frame, including a power shaft locatedin a plane below and intermediate the two drums, and a gear on saidpower shaft meshing with the gears on the winding drums and on therotating element and transmitting power toall of said gears.

Signed at New York city, in the borough of Brooklyn, county of Kings andState of New York, this 11 day of August, 1924.
